[pstricks] Problem with pst-tree and beamer

Hi all,

When I run the minimal example below I get the following error:

! Illegal parameter number in definition of \test.
<to be read again>
l.10 \end{frame}

The PSTricks part of the code is copied straight from pst-user.pdf and 
works fine outside of the frame environment -- it is only when I place 
it between \begin{frame} and \end{frame} that the error comes up.

Any ideas?



   \psset{armB=1cm, levelsep=3cm, treesep=1cm,
     angleB=-90, angleA=90, arrows=<-, nodesepA=3pt}
   \pstree[radius=2pt]{\Ttri{root}}{\TC* \TC* \TC* \TC*}
